Anti aging agent three-stage emulsifier

Continuous powder liquid mixer for anti-aging agents, continuous preparation device for anti-aging agents, online powder liquid mixer, dispersion equipment dedicated to quantitative online mixing of solids and liquids with high dispersion quality requirements. Accurate measurement of solid and liquid phases is required. Controlling the amount of raw materials can produce a ready-made product in only one channel.

Antioxidants are a type of rubber anti-aging agent with excellent performance, widely used in rubber industrial products such as tires and tapes. Phenylenediamine anti-aging agents have good protective effects against thermal oxidation, cracking, and flexural aging, and are also stabilizers for synthetic rubbers such as styrene butadiene rubber and isoprene rubber. There are many types of para phenylenediamine rubber anti-aging agents, mainly including: anti-aging agent N - (1,3-dimethylbutyl) - N '- phenyl para phenylenediamine (anti-aging agent 4020 or 6PPD), N-isopropyl-N' - phenyl para phenylenediamine (anti-aging agent 4010NA), N-sec octyl-N '- phenyl para phenylenediamine, etc.

General process

The use of intermittent kettle reaction to prepare anti-aging agents can significantly improve the conversion rate of the reaction, and the product quality and yield are also better than those in China. However, the intermittent kettle production capacity is low, the operation intensity is high, and the production process requires repeated temperature rise and fall, gas replacement, and loading and unloading of the reaction kettle, resulting in increased production costs, extended production cycles, and unstable product quality; Frequent filtration of the catalyst in intermittent reactions can easily lead to a significant loss of active components, greatly reducing the lifespan of the catalyst; In addition, batch reactor reactions are not suitable for large-scale industrial production.

Specially designed for quantitative online mixing of solids and liquids with high requirements for dispersion quality. Accurate measurement of solid and liquid phases is required. Controlling the amount of raw materials can produce a ready-made product in only one channel.

The XRS2000 solid-liquid dispersion mixer is equipped with three-stage dispersion, which can produce very fine suspensions even in rough raw materials. There are different types of stator rotor to adapt the machine to the product in the best possible way. This device is a specially designed model

The three-stage high shear dispersion machine is mainly used for the production of micro lotion and ultra-fine suspension lotion. Since three groups of dispersion heads (stator+rotor) in the working chamber work at the same time, after high shearing, the lotion drops are more delicate and the particle size distribution is narrower, so the stability of the generated mixed liquid is better. The three sets of dispersing heads are easy to replace and suitable for different process applications. The different models of machines in this series have the same line speed and shear rate, making it very easy to scale up production. It also meets the CIP/SIP cleaning standards and is suitable for food and pharmaceutical production.

High rotational speed and shear rate are important for obtaining ultrafine suspension lotion. According to some industry specific requirements, its shear rate can exceed 15000rpm, and the rotor speed can reach 44m/s. Within this speed range, turbulence caused by shear forces combined with specially developed motors can reduce the particle size range to the nanometer level. The shear force is stronger, and the particle size distribution of lotion is narrower.
